Ok, so here is my Zero Skin in the game update. @kursplat did shoot these over to me to take a look at, and bolt on my carb. took them to the track with me to throw on at the end of the night, and make a test run, and ran into an issue. The holes in these do not cleanly line up with my carburetor squirters (which is a 4150 based proform) fuel actually mists up and out of the carburetor when it contacts these "plates". if i press on the gas, the car runs notably rougher, as i would expect given what i'm seeing as fuel misting up and out (assuming to some kind of misalignment) called them several times with no answer, shot an email over also. so just a clean statement of fact, with MY carb, they don't seem to fit well enough to give an actual test. Now clearly there are a bunch of guys on youtube with them on and running (and prettily misting as advertised) , so not sure what i'm running into. Only thing i can report is they did not simply bolt on and work like magic. I'll report with what they say via email.
